This is the best adaptation of Frankenstein. I know what you are saying, it's not a super accurate Frankenstein. In fact, it's actually based off a story by Lovecraft and not Frankenstein at all. Wrong/Who cares? This is a movie about a doctor that re-animates the dead, so it is at least as accurate as most Frankenstein adaptations.

Re-Animator is a genuinely good goofy horror movie. You owe it to yourself to watch it.
